A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

Door lock assembly with safeguarding against bypassing

A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

Door lock assembly

A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

An electronic door lock system includes a gasket system for protecting electrical and mechanical components from exterior water and air. A lock portion may include a gasket, a circuit board, and a plate disposed between a first and second housing. The gasket includes an L-shaped perimeter that wraps around a first side and perimeter edge of the circuit board. The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.

A release mechanism is actuated by the heat of a fire to electrically and mechanically disconnect electrical wiring from an electronic lock having a plastic housing. The electronic lock is mounted on a fire door and as it is heated by a fire on the opposite side of the fire door, mounts that hold the lock melt, releasing the electronic lock to drop away from the fire door and prevent ignition of the plastic housing. The release mechanism may use shape memory alloy wire to contract and disconnect a ribbon cable. Solder connectors may also be used to disconnect wires. Intumescent material that expands when heated is used to drive the lock mechanism away from the fire door and insulation is used to control the timing of melting.

Escutcheon

An apparatus and method for releasably mounting access control components for a door lock to a door. A base element is adapted to be mounted to the door. A first wire connector element is mounted to the base element. A mounting element with combustible material attached is provided. A second wire connector element is mounted to the mounting element, and the second wire connector element is releasably connected to the first wire connector element to mount the mounting element to the base element. A spring is provided, and a retainer holds the spring in a loaded state, but in a fire event the retainer may melt, allowing the spring to apply force to the mounting element. Alternatively, an expanding material may apply the force. The force causes the wire connector elements to disconnect and allow the mounting element to separate from the base element.
